Description
FIELD OF THE INVENTION
[0001] The present invention relates, generally, to the field of
temporary structures. More particularly, the present invention
relates to clamps for sheeting material used as roofing for
temporary structure.
BACKGROUND OF THE INVENTION
[0002] Temporary structures typically use fabric panels as roofing
or walls to provide a wind and weather enclosure. These fabric
panels have fiber ropes sown onto the edges of the panel and can be
purchased under the trade name "Keder Panel." The edges of the
fabric panels with the ropes sewn in are inserted into open,
circular grooves in channels designed to secure and support the
panels.
[0003] One challenge with typical fabric panels is securing and
tensioning the loose ends of the fabric panels. Typically, the
fabric panels are specifically manufactured for a given
application. For example, at least in some applications, the fabric
panels are manufactured to a specific length and a specific width
to match the dimensions of a temporary structure. When setting up a
job site with a temporary structure, an engineer must therefore
create a drawing of the structure and a manufacturer must cut the
panels to the specified length and weld on the pockets for
receiving a structural member of the temporary structure to secure
the panel to the structure.
[0004] The process of designing panels, cutting panels to length
and welding pockets increases lead time and cost for each
project.
[0005] For at least these reasons, therefore, it would be
advantageous if a new or improved structure, system and/or method
for securing fabric panels to a temporary structure and/or using
bulk panels could be developed that addressed one or more of the
above-described concerns, and/or other concerns.
SUMMARY OF THE INVENTION
[0006] In an embodiment, a temporary structure sheet clamp
comprising a first clamping plate and a second clamping plate is
provided. The first clamping plate has a length and a pair of
opposed edges corresponding to the length and comprises a first
channel approximately parallel with the pair of opposed edges and
proximal to a first of the opposed edges, a second channel
approximately parallel with the pair of opposed edges and proximal
to a second of the opposed edges, the second channel further
comprising a plurality of openings therein, a first plurality of
apertures aligned approximately parallel with and proximal to the
first channel, and a second plurality of apertures aligned
approximately parallel with and proximal to the second channel. The
second clamping plate has a length and a pair of opposed edges
corresponding to the length and comprises a first channel
approximately parallel with the pair of opposed edges and
corresponding to the first channel of the first clamping plate, and
a first plurality of apertures aligned approximately parallel with
and proximal to the first channel and corresponding to the first
plurality of apertures of the first clamping plate. At least one
securing structure, when engaging at least one pair of apertures of
the first pluralities of apertures, secures the first clamping
plate and second clamping plate around a tubular structure around
which a sheet is wrapped.
[0007] In an embodiment, a temporary structure is provided. The
temporary structure comprises at least one fabric sheet comprising
a first end and a second end; at least three tubular components;
and at least one clamp. The clamp comprises a first clamping plate
and a second clamping plate. The first clamping plate has a length
and a pair of opposed edges corresponding to the length, and
further comprises a first channel approximately parallel with the
pair of opposed edges and proximal to a first of the opposed edges,
a second channel approximately parallel with the pair of opposed
edges and proximal to a second of the opposed edges, the second
channel further comprising a plurality of openings therein, a first
plurality of apertures aligned approximately parallel with and
proximal to the first channel, and a second plurality of apertures
aligned approximately parallel with and proximal to the second
channel. The second clamping plate has a length and a pair of
opposed edges corresponding to the length, and further comprises a
first channel approximately parallel with the pair of opposed edges
and corresponding to the first channel of the first clamping plate,
and a first plurality of apertures aligned approximately parallel
with and proximal to the first channel and corresponding to the
first plurality of apertures of the first clamping plate. The
fabric sheet is wrapped around a first of the tubular components
and secured between the first and second clamping plates at the
first channels of the clamping plates. At least one of the first
and second ends of the fabric sheet is secured to a second of the
tubular components. A third of the tubular components is secured in
the second channel of the first clamping plate.
[0008] In an embodiment, a method of forming a temporary structure
is provided. The method comprises wrapping a sheet around a first
tubular structure; providing a clamp structure comprising a first
clamping plate having a length and a pair of opposed edges
corresponding to the length, a first channel approximately parallel
with the pair of opposed edges and proximal to a first of the
opposed edges, and a second channel approximately parallel with the
pair of opposed edges and proximal to a second of the opposed
edges, the second channel further comprising a plurality of
openings therein; and a second clamping plate having a length and a
pair of opposed edges corresponding to the length, a first channel
approximately parallel with the pair of opposed edges and
corresponding to the first channel of the first clamping plate such
that when the plates are positioned with respect to one another,
the first channels form a tubular channel; aligning the tubular
structure in between a first and second clamping plate in the
tubular channel formed by the two first channels; securing the
first and second clamping plates around the tubular structure; and
securing a second tubular structure in the second channel, wherein
the second tubular structure is at least a portion of a temporary
structure.

DETAILED DESCRIPTION
[0030] In a first embodiment, such as shown in FIGS. 1A and 1B, a
sheeting clamp for a temporary structure 100 includes a first
clamping plate 10 (also referred to herein as the first plate 10)
and a second clamping plate 30 (also referred to herein as the
second plate 30). A plurality of securing structures 50 secures the
first and second clamping plates 10, 30 together.
[0031] As better viewed in FIGS. 2A-2C, the first clamping plate 10
has a first channel 13 extending the length of the plate 10
approximately parallel with the opposed edges 11a/11b. A second
channel 17 also extends the length of the plate 10 approximately
parallel with the opposed edges 11a/11b but contains a plurality of
openings 20 in the channel 17. In the embodiment shown, the second
channel 17 includes two openings 20. However, in further
embodiments, the second channel 17 on the first clamping plate 10
may have at least two, at least three, or at least four openings
20. In further embodiments, the second channel 17 may have two, or
three, or four openings 20. In yet a further embodiment, the second
channel 17 may contain more than two, or more than three, or more
than four openings 20.
[0032] In an embodiment, the openings 20 are approximately from 2
inches to 15 inches wide, or from 2 inches to 14 inches wide, or
from 3 inches to 13 inches wide, or from 4 inches to 12 inches. In
the embodiment shown in FIGS. 2A-2B, the openings 20 are from 9
inches to 14 inches wide, or from 10 inches to 13 inches wide, or
from 11 inches to 12 inches wide. In an embodiment, the openings 20
are 11.81 inches wide.
[0033] As illustrated in FIGS. 2A and 2B, in the embodiment shown,
the first channel 13 of the first plate 10 is approximately
semi-circular with the semi-circular shape formed by three surfaces
14a, 14b, 14c angled relative to one another. Surface 14a angles
outward from the plane of the first plate 10 and, in the view
shown, downward (e.g., in the direction of the second channel 17)
to surface 14b. In an embodiment, the surface 14a projects away
from the plane of the first plate 10 forming an angle A.sub.1 of
130-150.degree., or 135-145.degree., or 140.degree.. Surface 14b is
approximately parallel with first plate 10. Surface 14c angles back
towards the first plate 10 to complete the approximately
semi-circular first channel 13 and meets back with the first plate
10 forming an angle A.sub.2 of 130-150.degree., or 135-145.degree.,
or 140.degree.. In further embodiments, the first channel 13 may be
formed using any number of surfaces, including, for example, two
surfaces forming a "V"-like shape, or be a continuous curve.
[0034] By forming the first channel 13 using at least two (e.g.,
two, three, four) angled surfaces (e.g., 14a, 14b, 14c as shown) or
a single continuous curve, the first channel 13 has an approximate
inner diameter of 1-5 inches, or 1-3.5 inches, or 1-2 inches. In an
embodiment, the first channel 13 has an approximate inner diameter
of 2 inches, or 1.9 inches, or 1.8 inches. In an embodiment, the
first channel 13 preferably has an inner diameter of 1.9 inches. In
an embodiment, the inner diameter of the first channel 13
corresponds to the outer diameter of an approximately tubular
structure to which a fabric panel is secured. In a further
embodiment, the inner diameter of the first channel 13 corresponds
to the outer diameter of a scaffold tube.
[0035] As also illustrated in FIGS. 2A and 2B, in the embodiment
shown, the second channel 17 of the first plate 10 is a hook-like
shape formed by a plurality of surfaces 12a, 12b, 12c, 12d and 12e.
Surface 12a angles outward from the plane of the first plate 10 in
the same direction as surface 14a and, in the view shown, downward
(e.g., away from the first channel 13) to surface 12b. In an
embodiment, the surface 12a projects away from the plane of the
first plate 10 forming an angle A.sub.3 of 150-170.degree., or
155-165.degree., or 159-161.degree., or 160.7.degree.. Surface 12b
is approximately parallel with first plate 10 and forms an angle of
A.sub.4 of 150-170.degree., or 155-165.degree., or 159-161.degree.,
or 160.7.degree. relative to surface 12a. Surface 12c angles back
towards the first plate 10 forming an angle A.sub.5 of
120-140.degree., or 125-135.degree., or 128-132.degree., or
130-131.degree., or 130.3.degree. to connect with surface 12d which
is approximately perpendicular to the plane of the first plate 10.
The transition from surface 12c to 12d forms an angle A.sub.6 of
120-150.degree., or 130-145.degree., or 135-140.degree., or
139.7.degree.. Surface 12e projects away from surface 12d and, in
the view shown, upward from surface 12d (e.g., towards the first
channel 13) in order to complete the hook-like formation. In the
embodiment, surface 12e projects from surface 12d at an angle
A.sub.7 of 100-115.degree., or 105-112.degree., or 108-110.degree.,
or 109.3.degree..
[0036] The hook-like shape is interrupted (twice in the embodiment
shown) by openings 20. As will be shown with respect to FIG. 8, the
openings 20 allow a tension-applying structure or device 76 to be
connected to a tensioning component 70 which may be secured in the
second channel 17. In the embodiment shown in FIG. 8, the
tension-applying structure or device 76 is connected to both the
tensioning component 70 and a member 78 of a temporary structure
(not shown).
[0037] The first plate 10 also includes a first plurality of
apertures 15 which is aligned approximately parallel with and
proximal to the first channel 13. While in the embodiment shown,
each aperture of the plurality of apertures 15 contains a cage nut
16, the apertures 15 do not require a cage nut or other hardware
component or structure to be provided with the apertures 15. In the
embodiment shown, the first plurality of apertures 15 is inward of
the first channel 13 (e.g., below the first channel 13 in the
orientation shown in FIGS. 2A and 2B), but still proximal to the
first channel 13. If the first plurality of apertures 15 were
positioned outward of the first channel 13, any securing structure
engaging the plurality of apertures 15 would contact and
potentially damage a fabric panel secured in the clamp 100, as
illustrated more clearly with respect to FIG. 4.
[0038] In further embodiments, the first plurality of apertures 15
may be located further away from the first channel 13 in a
direction towards the second channel 17. However, the further away
from the first channel 13 the first plurality of apertures 15 is
positioned, the less clamping pressure is provided to hold a fabric
sheet for a temporary structure between the plates 10, 30. In a
preferred embodiment, the first plurality of apertures 15 is within
from 0.5 inches to 3 inches, or preferably from within 0.75 inches
to 2 inches, or preferably from within 1 inch to 2 inches of the
center of the first channel 13. In an embodiment, the first
plurality of apertures 15 is approximately 1.75 inches of the
center of the first channel 13.
[0039] A second plurality of apertures 19 is aligned approximately
parallel with and proximal to the second channel 17. As illustrated
in FIGS. 2A and 2B, in the embodiment show, the second plurality of
apertures 19 comprises sets of apertures (21a/21b, 22a/22b,
23a/23b) with a first aperture in the sets (21a, 22a, 23a)
positioned on surface 12a and a second aperture in the sets (21b,
22b, 23b) positioned on surface 12e.
[0040] As shown in FIGS. 3A and 3B, the second clamping plate 30
has a first channel 33 extending the length of the plate 30
approximately parallel with the opposed edges 31a/31b. As
illustrated in FIGS. 3A and 3B, in the embodiment shown, the first
channel 33 of the second plate 30 is approximately semi-circular
with the semi-circular shape formed by three surfaces 34a, 34b, 34c
angled relative to one another. Surface 34a angles outward from the
plane of the second plate 30 and, in the view shown, downward
(e.g., away from the flared lip 38) to surface 34b. In an
embodiment, the surface 34a projects away from the plane of the
second plate 30 forming an angle A.sub.8 of 130-150.degree., or
135-145.degree., or 140.degree.. Surface 34b is approximately
parallel with second plate 30. Surface 34c angles back towards the
second plate 30 to complete the approximately semi-circular first
channel 33 and meets back with the second plate 30 forming an angle
A.sub.9 of 130-150.degree., or 135-145.degree., or 140.degree.. In
further embodiments, the first channel 33 may be formed using any
number of surfaces or be a continuous curve.
[0041] By forming the first channel 33 using surfaces (e.g., 34a,
34b, 34c as shown), the first channel 33 has an approximate inner
diameter of 1-5 inches, or 1-3.5 inches, or 1-2 inches. In an
embodiment, the first channel 33 has an approximate inner diameter
of 2 inches, or 1.9 inches, or 1.8 inches. In an embodiment, the
first channel 33 preferably has an inner diameter of 1.9 inches. In
an embodiment, the inner diameter of the first channel 33
corresponds to the outer diameter of an approximately tubular
structure to which a fabric panel is secured. In a further
embodiment, the inner diameter of the first channel 33 corresponds
to the outer diameter of a scaffold tube.
[0042] The second plate 30 also includes a first plurality of
apertures 35 which is aligned approximately parallel with and
proximal to the first channel 33. In the embodiment shown, the
first plurality of apertures 35 is inward of the first channel 33
(e.g., below the first channel 33 in the orientation shown in FIGS.
3A and 3B), but still proximal to the first channel 33. If the
first plurality of apertures 35 were positioned outward of the
first channel 33, any securing structure engaging the plurality of
apertures 35 would contact and potentially damage a fabric panel
secured in the clamp 100, as illustrated more clearly with respect
to FIG. 4.
[0043] In further embodiments, the first plurality of apertures 35
may be located further away from the first channel 33 in a
direction away from the flared lip 38. However, the further away
from the first channel 33 the first plurality of apertures 35 is
positioned, the less clamping pressure is provided to hold a fabric
sheet for a temporary structure between the plates 10, 30. In a
preferred embodiment, the first plurality of apertures 35 is within
from 0.5 inches to 3 inches, or preferably from within 0.75 inches
to 2 inches, or preferably from within 1 inch to 2 inches of the
center of the first channel 13. In an embodiment, the first
plurality of apertures is approximately 1.75 inches of the center
of the first channel 13.
[0044] As illustrated in FIGS. 1A and 1B, the first pluralities of
apertures 15, 35 of the first and second clamping plates 10, 30,
respectively are aligned with one another so as to form a plurality
of holes through the first and second clamping plates 10, 30 when
the plates 10, 30 are positioned with respect to one another to
clamp a fabric sheet, such as in FIG. 4.
[0045] The first pluralities of apertures 15, 35 are configured to
receive a securing structure 50, such as, for example, a bolt,
screw, nail, rod, clip, clasp or other structure or device. In the
embodiment shown, each aperture of the first pluralities of
apertures 15, 35 are configured to receive a securing structure 50
which is a bolt that further engages the cage nuts 16 of the first
plurality of apertures 15 of the first clamping plate 10. In an
embodiment, as shown in FIG. 1A, the securing structures 50 further
include a graspable end 51 for manual manipulation (e.g.,
tightening and/or loosening by turning) or manipulation by a manual
or powered tool.
[0046] Similarly, the each second plurality of apertures 19 of the
first plate 10 may be configured to receive a securing structure,
such as, for example, a bolt, screw, nail, rod, clip, clasp or
other structure or device. However, in the embodiment shown in
FIGS. 5A-5C, such securing structure are unnecessary because the
tension applied by a tension-applying structure or device is
sufficient to ensure a tensioning component 70 in the second
channel 17, as in the embodiment shown in FIG. 8.
[0047] In an embodiment, the first and second plates 10, 30 further
include a flared lip 18, 38. The flared lip 18, 38 causes the edge
of the first and second clamping plates 10, 30 to be turned outward
away from the first channels 13, 33. As will be shown with respect
to FIGS. 4-5C, when a fabric panel is slid into the channel formed
by the first channels 13, 33, the fabric panel is not in contact
with an edge of the first and second plates 10, 30 and potential
damage (e.g., tears, rips, punctures) from contact with an edge is
avoided.
[0048] In some embodiments, such as shown in FIGS. 1A-3B, the first
clamping plate 10 may further include at least one aligning
aperture 26 configured to engage an at least one aligning
protuberance 46 of the second clamping plate 30. In the embodiment
shown, the first plate 10 includes a plurality of aligning
apertures 26 and the second plate 30 includes a plurality of
aligning protuberances 46, each of which corresponds to a
respective one of the plurality of aligning apertures 26.
[0049] In the embodiment shown, the aligning apertures 26 are
rectangular slots located parallel to and proximal with the second
channel 17. Specifically, in the embodiment, shown, the aligning
apertures 26 are inward from (e.g., above, in the view shown in
FIGS. 2A and 2B) the second channel 17. As further shown in the
embodiment depicted in FIGS. 1A-3B, the aligning protuberances 46
are rectangular bends projecting away from (e.g., downward from, in
the view shown) opposed edge 31b. Specifically, as shown in FIGS.
3A and 3B, the opposed edge 31b projects approximately
perpendicularly, or preferably perpendicularly, from the plane of
the second plate 30 in a direction opposite that of the first
channel 33. The aligning protuberances 46 comprise a first portion
47a which projects further outward from and parallel with the
opposed edge 31b and a second portion 47b which turns approximately
perpendicular to, or perpendicular to, the first portion 47a in a
direction that further from (e.g., downward from, in the view
shown) the second clamp plate 30 so as to be parallel with the
first plate 30.
[0050] When assembling the clamp 100, the second plate 30 is tipped
approximately perpendicular relative to the first plate 10 such
that the second portions 47b of the aligning protuberances 46
engage the aligning apertures 26 of the first plate 10. As the
aligning protuberances 46 further engage the aligning apertures 26,
the second plate 30 is rotated to become approximately parallel
with the first plate 10 such that the first portions 47a of the
aligning protuberances 46 engage the aligning apertures 26 and the
first channels 13, 33 of the first and second plates 10, 30,
respectively align to form a single first tubular channel 80, as
shown in FIGS. 1A and 1B.
[0051] Once the first and second plates 10, 30 are by the aligning
apertures and protuberances 26/46, the securing structures 50 are
used to at least partially engage the first pluralities of
apertures 15, 35. For example, in the exemplary embodiment shown,
the securing structures 50 are loosely engaged in the first
pluralities of apertures 15, 35. This partial engagement allows a
fabric panel (or at least a portion thereof) to slidingly engage
the first tubular channel 80.
[0052] In the embodiment shown, the fabric panel 60 (or portion
thereof) is secured around a cylindrical structure 65, such as a
scaffold tube, rope or other tubular component. The clamp 100 can
slide over cylindrical structure 65 so that the cylindrical
structure 65 is positioned in the first tubular channel 80 with the
fabric panel 60 projecting out of the clamp 100 at the flared lips
18, 38.
[0053] Once the fabric panel 60 is in position, the securing
structures 50 are tightened to compress the first and second plates
10, 30 and secure the cylindrical structure 65 in the first tubular
channel 80.
[0054] As illustrated in FIGS. 5A-5C, the second channel 17 secures
a tensioning component 70. In the embodiment shown, the tensioning
component 70 is another cylindrical structure, such as a scaffold
tube, rope or other tubular structure which can be used to support
tension to pull the fabric sheet 60 taut when the loose end (not
shown) of the fabric panel 60 is secured to at least a portion of a
temporary structure. In other words, the tensioning component 70
serves as a brace to which a tension-applying structure or
tensioning device 76 (not shown) is secured to provide a force
capable of pulling on the clamp 100 and making the fabric sheet 60
taut. In the embodiment illustrated in FIG. 8, the tension-applying
structure or device 76 is a tensioning strap. In other embodiments,
the tension-applying structure or device 76 may be a rope, clamp,
clip, pulley system or other structure or device capable of
applying tension by connection to the tensioning component 70.
[0055] In view of the above, it is desirable that channels 13 and
33 have the same inner diameter. As will be appreciated, and as
depicted in FIGS. 5A-5C, when plates 10 and 30 are aligned with
respect to one another, the respective first channels 13, 33 align
to form an approximately tubular channels 80 into which tube 65 is
positioned. In an embodiment, the inner diameter of tubular channel
80 is approximately 1-5 inches, or 1-3.5 inches, or 1-2 inches. In
an embodiment, the inner diameter of tubular channel 80 is
approximately 2 inches, or 1.9 inches, or 1.8 inches. In an
embodiment, channel 80 has an inner diameter of 1.9 inches.
[0056] Similarly, the second channel 17 of the first plate 10 in
essence forms a second tubular channel 81 into which the tensioning
component 70 is positioned. In an embodiment, the inner diameter of
tubular channel 81 is approximately 1-5 inches, or 1-3.5 inches, or
1-2 inches. In an embodiment, the inner diameter of tubular channel
81 is approximately 2 inches, or 1.9 inches, or 1.8 inches. In an
embodiment, the tubular channel 81 has an inner diameter of 1.9
inches.
[0057] In an embodiment, it is desirable that the inner diameter of
tubular channel 80 is the same as the inner diameter of tubular
channel 81.
[0058] FIGS. 6A-6B show a second embodiment of a sheeting clamp for
a temporary structure 100' in which both the first and second clamp
plates 10', 30' are identical. Like clamp 100, the first and second
plates 10', 30' of the clamp 100' contain a first channel 13', 33'
which extends the length of the plates 10', 30' and is
approximately parallel with the opposed edges 11a'/11b', 31a'/31b'.
However, instead of a second tubular channel 80 formed entirely by
the second channel 17 of the first panel 10, as in with respect to
clamp 100, in the embodiment shown in FIGS. 6A-7B, both the first
and second plates 10', 30' contain a second channel 17', 37' also
extending the length of the plates 10', 30' approximately parallel
with the opposed edges 11', 31' to form a second tubular channel
81', as discussed in further detail below.
[0059] As shown, the second channels 17', 37' include a plurality
openings 20', 40'. In the embodiment shown, the second channels
17', 37' include two openings 20', 40'. However, in further
embodiments, the second channels 17', 37' may have at least two, at
least three, or at least four openings 20'. In further embodiments,
the second channels 17'/37' may have two, or three, or four
openings 20'. In yet a further embodiment, the second channels
17'/37' may contain more than two, or more than three, or more than
four openings 20'.
[0060] In an embodiment, the openings 20' are approximately from 2
inches to 15 inches wide, or from 2 inches to 14 inches wide, or
from 3 inches to 13 inches wide, or from 4 inches to 12 inches. In
the embodiment shown in FIGS. 7A-2B7, the openings 20' are from 2
inches to 7 inches wide, or from 3 inches to 6 inches wide, or from
3.5 inches to 5 inches wide. In an embodiment, the openings 20' are
4 inches wide.
[0061] As shown and described with respect to FIG. 8, the openings
20' allow a tension-applying structure or device 76 to be connected
to a tensioning component 70 which may be secured in the second
channel 17'.
[0062] As illustrated in FIGS. 7A-7B, in the embodiment shown, the
first and second channels 13', 33', 17', 37' are approximately
semi-circular with the semi-circular shape formed from a continuous
curve instead of multiple angled surfaces as in clamp 100. However,
in an alternative embodiment, any of channels 13', 33', 17', 37'
may be formed using a plurality of angles surfaces, as described
with respect to channels 13 and 33.
[0063] Like clamp 100, semi-circular channels 13', 33', 17', 37'
have an approximate inner diameter of 1-5 inches, or 1-3.5 inches,
or 1-2 inches. In an embodiment, the channels 13', 33', 17', 37'
each have an inner diameter of approximately 2 inches, or 1.9
inches, or 1.8 inches. In an embodiment, each of the channels 13',
33', 17', 37' has an inner diameter of 1.9 inches. In an
embodiment, the inner diameter of the channels 13', 33', 17', 37'
corresponds to the outer diameter of an approximately tubular
structure to which a fabric panel is secured. In a further
embodiment, the inner diameter of the channels 13', 33', 17', 37'
corresponds to the outer diameter of a scaffold tube.
[0064] In an embodiment, it is desirable that channels 13' and 33'
have the same inner diameter and channels 17' and 37' have the same
inner diameter. Still preferably, it is desirable that each of
channels 13', 33', 17' and 37' have the same inner diameter.
[0065] As will be appreciated, and as depicted in FIGS. 6A-6B, when
plates 10' and 30' are aligned with respect to one another, the
respective first channels 13', 33' and respective second channels
17', 37' align to form two approximately tubular channels 80', 81'
(not shown) into which tubes 65, 70 are positioned. In an
embodiment, the inner diameter of tubular channels 80', 81' is
approximately 1-5 inches, or 1-3.5 inches, or 1-2 inches. In an
embodiment, the inner diameter of tubular channels 80', 81' is
approximately 2 inches, or 1.9 inches, or 1.8 inches. In an
embodiment, each of channels 80', 81' has an inner diameter of 1.9
inches.
[0066] In an embodiment, it is desirable that tubular channels 80',
81' have the same inner diameter.
[0067] The first and second plates 10', 30' also include at least
first pluralities of apertures 15', 35' and second pluralities of
apertures 19', 39'. In the embodiment shown, the first pluralities
of apertures 15', 35' is inward of the first channels 13', 33'
(e.g., below the first channels 13', 33' in the orientation shown
in FIGS. 7A and 7B), but still proximal to the first channels 13',
33'.
[0068] In further embodiments, the first pluralities of apertures
15', 35' may be located further away from the first channels 13',
33' in a direction towards the second channels 17', 37' (e.g.,
above the first channels 13', 33' in the orientation shown in FIGS.
7A and 7B). If the first pluralities of apertures 15', 35' were
positioned outward of the first channels 13', 33', any securing
structure engaging the apertures would contact and potentially
damage a fabric panel secured in the clamp 100', as described more
fully above with respect to FIGS. 1A-3B. In further embodiments,
the first pluralities of apertures 15', 35' may be located further
away from the first channels 13', 33' in the direction of the
second channels 17', 37'. However, the further away from the first
channels 13', 33' the first pluralities of apertures are, the less
clamping pressure is provided to hold a fabric sheet for a
temporary structure between plates 10', 30'. In a preferred
embodiment, the first pluralities of apertures 15', 25' are within
0.5 inches to 3 inches, or preferably from within 0.75 inches to 2
inches, or preferably from within 1 inch to 2 inches of the center
of the first channels 13', 33'. In an embodiment, the first
pluralities of apertures 15', 35' are within approximately 1.80
inches of the center of the first channels 13', 33.
[0069] Second pluralities of apertures 19', 39' are aligned
approximately parallel with and proximal to the second channels
17', 37'. In contrast to the sets of apertures which made the
second plurality of apertures 19 described with reference to FIGS.
2A and 2B, above, the apertures of both second pluralities of
apertures 19', 39' are single apertures.
[0070] Like described with reference to the first pluralities of
apertures 15', 35', the second pluralities of apertures 19', 39'
need to be close enough to the second channels 17', 37' such that
the clamping pressure provided by securing structures 50' (not
shown) engaging the pluralities of apertures 19', 39' is sufficient
to hold a tensioning component 70 in the second tubular channel 81'
formed by the second channels 17', 37' of the first and second
plates 10', 30'. The further away from the second channels 17', 37'
the second pluralities of apertures 19', 39' are, the less clamping
pressure created. In a preferred embodiment, the second pluralities
of apertures 19', 39' are within 0.5 inches to 3 inches, or
preferably from within 0.75 inches to 2 inches, or preferably from
within 1 inch to 2 inches of the center of the first channels 19',
39'. In an embodiment, the first pluralities of apertures 19', 39'
are within approximately 1.80 inches of the center of the first
channels 19', 39'.
[0071] As illustrated in FIGS. 6A and 6B, each aperture in the
first plurality of apertures 15' of the first plate 10' corresponds
to a respective aperture of the first plurality of apertures 35' of
the second plate 30'. Similarly, each aperture of the second
plurality of apertures 19' of the first plate 10' corresponds to a
respective aperture of the second plurality of apertures 39' of the
second plate 30'. In other words, the first pluralities of
apertures 15', 35' are aligned with one another so as to form a
plurality of holes through the first and second clamping plates
10', 30' and the second pluralities of apertures 19', 39' are
aligned with one another so as to form a plurality of holes through
the first and second clamping plates 10', 30' when the plates 10',
30' are positioned with respect to one another to clamp a fabric
sheet, such as in FIGS. 6A and 6B.
[0072] The pluralities of apertures 15', 35' and 19', 39' are
configured to receive a securing structure 50' (not shown), such
as, for example, a bolt, screw, nail, rod, clip, clasp or other
structure or device, and as further described in detail with
respect to FIGS. 1A-5C.
[0073] In the embodiments shown in FIGS. 6A-7B, the plates 10', 30'
include additional pluralities of apertures 49', 59', respectively,
each also configured to receive a securing structure 50'. The
additional pluralities of apertures 49', 59' provide further
flexibility when securing a fabric sheet 60 (not shown) and/or
tensioning component 70 (not shown) to the clamp 100'.
[0074] In an embodiment, the first and second plates 10', 30'
further include flared lips 18', 38'. As described above, the
flared lips 18', 38' help prevent potential damage (e.g., tears,
rips, punctures) to a fabric panel 60 from contact with an
edge.
[0075] When assembling the clamp 100', first and second plates 10',
30' are aligned with one another such that the first channels 13',
33' and second channels 17', 37' align to form first and second
tubular channels 80', 81', respectively (see FIGS. 6A and 6B).
[0076] Once the first and second plates 10', 30' are aligned,
securing structures 50' (not shown) are used to at least partially
engage one of the pluralities of apertures 15' and 35', 19' and
39', 49' or 59' to allow a fabric panel 60 (or at least a portion
thereof) and/or a tensioning component 70 (or at least a portion
thereof) to slidingly engage the first and/or second tubular
channels 80', 81', respectively.
[0077] In the embodiment shown, the fabric panel 60, tensioning
components 70 and tension-applying structure of device 76 are as
described with respect to FIGS. 4-5C.
[0078] In embodiments, clamps 100, 100' may be any length suitable
to secure and tension a fabric panel 60. In a preferred embodiment,
clamps 100, 100' have a length of 0.5-20 feet, or 1-15 feet, or
1-10 feet, or 2-10 feet. In an embodiment, the clamps 100, 100' are
available in different lengths to accommodate particular uses,
temporary structures and/or construction limitations/parameters. In
an embodiment, clamps 100, 100' have a length of approximately 2-5
feet, for preferably from 2-4 feet, or preferably 3 feet. In an
embodiment, clamps 100, 100' have a length selected from the group
consisting of approximately 1 foot, 3 feet, 5 feet, 7 feet, and 10
feet.
[0079] In an embodiment, clamps 100, 100' have a height of
approximately 8-16 inches, or preferably 9-15 inches, or preferably
10-14 inches, or preferably 11-13 inches, or preferably 12
inches.
[0080] In an embodiment, clamps 100, 100' have a thickness of
approximately 1-5 inches, or 2-4 inches, or 2-3 inches, or 2.5
inches.
[0081] The dimensions of clamps 100, 100' may vary depending on the
specific application, project and temporary structure being
assembled.
[0082] Because temporary structures are built in varying sizes,
providing clamps 100, 100' capable of using standard cylindrical
structures 65, such as, for example, scaffold tubes, to secure and
tension fabric panels 60, it is no longer necessary to specifically
manufacture panels for specific jobs. A bulk roll of fabric may be
used, cut to width and simply wrapped around a cylindrical
structure 65.
[0083] Furthermore, providing clamps 100, 100' in standard lengths,
such as, for example, lengths corresponding to standard scaffold
tube length, specialized clamping equipment becomes unnecessary.
For example, standard scaffold tubes come in various lengths,
including (by imperial measurement), 1 foot, 3 feet, 5 feet, 7
feet, 8 feet and 10 feet lengths. By providing clamps 100, 100'
having lengths corresponding to the shortest scaffold tubes (e.g.,
1 foot, 3 foot and/or 5 foot length), a single clamp length (or
combination of clamp lengths) can be used for all jobs. As
illustrated in FIGS. 6A and 6B, the cylindrical structure 65 around
which the fabric panel 60 is wrapped is a 10 foot length scaffold
tube. Each clamp 100' is 3 feet in length. To secure and tension
the fabric panel 60, three clamps 100' are used. Remaining room on
the ends of the cylindrical structure 65 and tensioning component
70 allow the cylindrical structure 65 and tensioning component 70
to be secured to a temporary structure as needed.
[0084] FIG. 8 shows the clamp 100 securing a fabric panel 60 with
tension-applying structures or devices 76 applying tension to the
tensioning component 70 to pull the fabric panel 60 taut, or at
least tight enough to provide a barrier for a temporary structure
(not shown). In the embodiment illustrated, fabric panel 60 is
secured around cylindrical structure 65 and further secured between
two rail members 79 of a temporary structure (not shown). The
tension-applying structures or devices 76 are secured to and/or
around a further member 78 of the temporary structure (not shown)
and the tensioning component 70. Tightening the tension-applying
structures 76 results in the fabric panel 60 being stretch and
pulled tighter on the temporary structure (not shown).
[0085] FIG. 9 shows a temporary structure 150 using fabric sheets
60 (not labeled) as a roof 152 for the temporary structure 150.
Portion X is shown in further detail in FIG. 10.
[0086] As shown in FIGS. 9 and 10, the fabric sheets 60 are secured
between rail members 79 of the temporary structure 150. At one end
(e.g., the bottom end as shown in the exemplary embodiments of
FIGS. 9 and 10), the fabric sheets 60 are secured to the temporary
structure 150 using clamps 100. The other end (e.g., the upper end
as shown in the exemplary embodiments of FIGS. 9 and 10), the
fabric sheets are connected to the temporary structure 150 using,
for example, either a further clamp 100, a further rail member 79,
a pocket connect as known and currently used in the art, or other
structure or device useful in securing the panel 60 to the
temporary structure 150.
[0087] In the embodiment shown in FIGS. 9 and 10, the members 78
are tension bars which are also secured between rail members
79.
[0088] As the tension-applying structures or devices 76 tighten,
tension components 70 are pulled closer to members 78, causing the
clamps 100 to move towards members 78 (e.g., in the view shown,
downward). As the clamps 100 are pulled towards members 78, the
fabric sheets 60 are pulled and stretched. Tension-applying
structures or device 76 can continue to tighten until a desired
tension on the fabric sheets 60 is reached (e.g., a tension desired
for a specific temporary structure application or the maximum
tension the fabric sheets can withstand).
[0089] In an embodiment, a method of forming a temporary structure
200 is provided, as shown in FIG. 11.
[0090] A first step 205 comprises wrapping a sheet around a first
cylindrical structure. In an embodiment, the cylindrical structure
is a tubular structure. In a further embodiment, the tubular
structure is a scaffold tube.
[0091] Step 210 comprises providing a clamp structure, such as
described with reference to one or more of FIGS. 1A-7B, above.
[0092] Step 215 comprises positioning/aligning the first
cylindrical structure in between a first and second clamping plate
of the clamp structure such that the cylindrical structure is
positioned in a tubular channel formed by the first and second
clamping plates.
[0093] Step 220 comprises at least partially securing the first and
second plates around the cylindrical structure.
[0094] Step 225 comprises securing a tensioning component in a
second channel of the clamp. In an embodiment, the tensioning
component is a second cylindrical structure is a tubular structure,
further a scaffold tube. In an embodiment, the tensioning component
is a second cylindrical structure which is at least a portion of
the temporary structure, further a scaffold tube which is at least
a portion of the temporary structure.
[0095] In an embodiment, step 215 comprises positioning the first
and second clamping plates relative to one another such that a
first channel in the first plate and a first channel in the second
plate form a first tubular channel and sliding the first
cylindrical structure into the first tubular channel.
[0096] In an embodiment, the first and second clamping plates are
at least partially secured to one another using one or more
securing structures before the first cylindrical structure is
aligned in between the clamp plates. The first and second plates
may then be further secured in step 220.
[0097] In an embodiment, the step 215 comprises positioning a first
plate with respect to the first cylindrical structure such that the
first cylindrical structure engages a first channel of the first
plate and positioning a second plate with respect to the first
cylindrical structure such that the first cylindrical structure
also engages a first channel of the second plate in order to
sandwich the first cylindrical structure between the first and
second plates.
[0098] In an embodiment, the step 220 of at least partially
securing the first and second clamping plates together around the
cylindrical structure comprises securing the plates together using
at least one securing structure, as described above. However, in
further embodiments, and particularly if a tensioning component is
also to be secured between the plates, the step 220 of at least
partially securing the first and second clamping plates together
may include temporarily securing the plates together, such as
holding them in position by hand or using a securing structure as
described herein.
[0099] In an embodiment, the step 225 of securing a tensioning
component in a second channel of the clamp comprising sliding the
tensioning component into a second channel of the first clamp plate
and securing the tensioning component in the channel. In a further
embodiment, the step 225 comprises sliding the tensioning component
into a second tubular channel formed by the first and second clamp
plates and further securing the plates together such that both the
first cylindrical structure and tensioning component are sandwiched
between the plates.
[0100] In a further embodiment, the step 225 of securing the
tensioning component comprises positioning the first plate with
respect to the tensioning component and first cylindrical structure
such that the first cylindrical structure engages the first channel
of the first plate and the tensioning component engages a second
channel of the first plate and positioning a second plate with
respect to the first cylindrical structure and tensioning component
such that the first cylindrical structure also engages the first
channel of the second plate and the tensioning components also
engages a second channel of the second plate such that both the
first cylindrical structure and tensioning component are sandwiched
between the plates.
[0101] In an embodiment, the method further includes the steps of
230 securing a tension-applying structure or device to the
tensioning component and applying tension to pull the sheet taut.
In an embodiment, the taut sheet forms a surface of a temporary
structure, such as, for example, a wall or roofing panel.
[0102] Among other things, it should be appreciated that the scope
of the present disclosure is not limited to the number of
constituting components, the materials thereof, the shapes thereof,
the relative arrangement thereof, etc., as described above, but
rather the above disclosures are simply provided as example
embodiments.
[0103] Thus, it is specifically intended that the present invention
not be limited to the embodiments and illustrations contained
herein, but include modified forms of those embodiments including
portions of the embodiments and combinations of elements of
different embodiments as come within the scope of the following
claims.
